WARNING
Never look at the Sun while using your spotting scope.
Looking at the Sun can cause permanent eye damage.
BEFORE UsE
Attach your spotting scope to a sturdy tripod before viewing
as the size and power of the spotting scope requires a solid
tripod for stability to achieve clear, sharp images (Fig. 2).
AttAching thE EyEpiEcE
A zoom eyepiece is included with the Regal M2 spotting
scope. To attach the eyepiece to the spotting scope, turn
the eyepiece lock collar counterclockwise until it is loose
and remove the eyepiece mount cover. Make sure that the
protective lens cap is removed from the eyepiece and slide
it into the eyepiece mount (Fig. 3a). When the eyepiece
is fully seated turn the lock collar clockwise to secure the
eyepiece and hold it in place (Fig 3b). Do not attempt to
attach or remove the eyepiece without first loosening the
lock collar as it can cause damage to the eyepiece and/or
the spotting scope.

EyEcUp AdjUstmEnt
The included zoom eyepiece of the Regal M2 features a
twist-up eyecup to accommodate both eyeglass and non-
eyeglass wearers (Fig. 4). If you do not wear eyeglasses,
twist the eyecup counterclockwise until it reaches the up
position. If you wear eyeglasses, make sure that the eyecup
is in the down position to obtain the maximum field of
view. The eyecup can be set at positions between fully up
and down which may suit some users better.
chAnging thE mAgniFicAtiOn
To change the magnification of the zoom eyepiece simply
rotate the eyepiece in the counterclockwise direction to
increase the magnification and clockwise to decrease
the magnification (Fig 5). When changing magnification
the scope will need to be refocused. The largest field of
view and brightest images will always be at the lowest
magnification.
FOcUsing
To ensure a crisp, sharp image the spotting scope must be
focused. The Regal M2 features a dual focus system that
includes a course and a fine focus (Fig. 6). To focus the
spotting scope, slowly rotate the course focus knob until
the image in the eyepiece is clear and sharp. For fine

adjustment slowly rotate the fine focus knob (located
in front of the course focus knob) until the image in the
eyepiece is clear and sharp. When the focus knob will not
rotate any further, turn the wheel in the opposite direction.
ROtAting tRipOd mOUnt
The Regal M2 features a rotating tripod mount that rotates
a full 360° and allows the eyepiece to be set in any viewing
position. To change the position of the eyepiece, loosen
the lock screw located on the tripod mount and turn the
scope to the desired position (Fig 7a, 7b). Tighten the lock
screw and view through the eyepiece.
lEns shAdE And sighting gUidE
The lens shade of the Regal M2 will slide away from the
body to protect the lens from exposure to rain or to keep
unwanted glare from entering the spotting scope and
degrading your image. A sighting guide is molded into
the lens shade rubber to aid in locating your subject and
bringing it into the field of view (Fig. 8). The location of the
sighting guide can be changed by simply rotating the lens
shade.

OptiOnAl EyEpiEcEs
The Regal M2 Series spotting scopes were designed to use optional 1.25” eyepieces. Celestron offers a wide
selection of 1.25” eyepieces for use on your spotting scope to achieve higher magnifications, wider fields of
view, etc.
BAlAncE plAtE (FOR thE 100 mm mOdEl)
The Regal M2 100 mm spotting scope comes with a
balance plate to properly balance the spotting scope
when attached to a tripod (Fig. 9). To use the balance
plate, mount it to the tripod’s ¼”-20 mounting screw
using the ¼”-20 threaded hole located on the bottom of
the plate. Attach the spotting scope to the balance plate
using the ¼”-20 mounting screw located on the top of
the plate and thread it into the spotting scope as far
as it will go. Slide the spotting scope along the slotted
portion of the plate until the spotting scope is balanced
on the tripod. Tighten the locking ring to hold the
spotting scope in the desired position.
digiscOping
The Regal M2 spotting scopes can be used for digiscoping with SLR cameras and point-and-shoot digital
cameras. Please note that not all cameras are compatible for digiscoping and in some cameras vignetting
(a circular image surrounded by black) will occur. Point-and-shoot cameras with an optical zoom of 3x or 4x
tend to be the most compatible with the least amount of vignetting. Most photographs will be the sharpest
and brightest when using the lowest magnification on the zoom eyepiece.

slR phOtOgRAphy
To use an SLR camera and your spotting scope for photography,
you will shoot through the zoom eyepiece while it is attached to
the spotting scope. To prevent damage to the spotting scope,
eyepiece or camera make sure the eyepiece lock collar is secure
during each stage of the setup.
1. Remove the eyecup from the zoom eyepiece. With the
eyecup down, rotate it counterclockwise to remove it
from the eyepiece. This will expose the threads under
the eyecup (Fig. 10a).
2. Thread the included T-adapter ring to the threads
exposed on the eyepiece in step one above (Fig. 10b).
3. Thread an optional T-ring for your make and model of
camera onto the T-adapter ring (Fig. 10c)
4. Attach your SLR camera body to the T-ring (Fig. 10d).
The Regal M2 spotting scopes have fixed apertures and as a
result fixed f/ratios. To achieve the proper exposure for your
photographs you need to set the shutter speed accordingly.
Most cameras offer through-the-lens metering which will let
you know if your picture is under or overexposed. Consult your
camera manual for specific information on metering, changing
shutter speeds and other settings.

pOint-And-shOOt phOtOgRAphy
A variety of point-and-shoot cameras can be used to
digiscope with the Regal M2 spotting scopes utilizing the
Universal Camera Adapter (#93626) offered by Celestron
(Fig. 11). This adapter attaches to the spotting scope’s
eyepiece and allows the camera lens to be centered
behind the eyepiece. Please note that not all cameras
are compatible with this adapter as there is not enough
adjustment to center the lens behind the eyepiece when
the position of the lens is low in the camera body or when
the camera does not have adequate height.
WAtERpROOF / FOgpROOF
The Regal M2 Series spotting scopes are waterproof and filled with dry nitrogen gas to prevent the housing
from fogging internally.
cARE And stORAgE
Your Celestron spotting scope will provide you years of dependable service if it is cared for and stored
properly.
1. Protect the spotting scope from impact and do not force any of the moving parts beyond their limits.
2. Protect the optics of your spotting scope by putting on all lens caps when not in use.
3. Store your spotting scope in a cool, dry place whenever possible.
4. When storing for an extended period of time, place the spotting scope in a plastic bag or airtight
container with a desiccant.
Fig. 11
5. Do not leave the spotting scope in a car on a hot/sunny day or near anything that generates heat as this
may cause damage.
6. Clean any dust, dirt or water that may get on the spotting scope or inside moving parts as soon as possible
to prevent any unforeseen damage.
clEAning
Proper lens cleaning is essential to maintaining the optical integrity of your spotting scope. Dirty lenses diminish
the amount of light transmitted through the spotting scope and your overall viewing experience.
1. Remove any dust on the lenses with a soft lens brush or can of pressurized air.
2. Remove any fingerprints, stains or smudges from the lens surface with a soft, clean lens cloth or lens tissue
by rubbing in a circular motion. Start in the middle of the lens and work your way to the edges. Breathe
lightly on the lens to provide moisture if needed.
3. For a more thorough cleaning we recommend the use of a lens/optics cleaning kit available at most photo
or optical shops. Follow the directions supplied with the cleaning kit for best results.
sERvicE And REpAiR
